In Windows, each domain user gets a unique SID. If you're using "domain
level" security in Samba, Samba will get the user SID (as well as domain
SID & group SIDs) from the PDC if validation is successful.

The user's SID is not stored because Samba does not have any use for
it locally. Samba will map the windows user to his/her Unix account 
and use the corresponding uid to identify the user locally.

The client sends the credentials to the server it is trying to connect
to - it does not attempt to validate the user locally.
